"Failed to apply a new address"

I want to deposit some TKY into kucoin using the mobile app but when I select the coin no wallet address appears and instead I have the message "failed to apply a new address".
Other coins (ETH, BTC, LTC) are working fine though.
What's the problem and will it be working again soon?
Edit: This issue has now been resolved. I'm not sure what the issue was, but it must have just been linked to my account as other users didn't seem to have the same problem. The support team were very quick in replying to my issue. Thanks
